CENTRIFUGAL LlQUID-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 667,329, dated February5, 1901.

Application filed October 5, 1900. Serial No. 32,090. (No model.)

To (0Z5 whom, it may concern/.-

Be it known that we, WILBUR W. MARSH and CHARLES H. HACKETT, citizens ofthe United States of America,and residents of Waterloo, Black Hawkcounty,lowa,have invented certain new and useful Improvements inCentrifugal Liquid-Separators, of which the following is aspecification.

Our invent-ion relates to that class of separators in which liquidswhose constituents are of difierent specific gravities are separated bycentrifugal force, and has for one of its objects the provision ofsegmental conical plates movably attached to an interior liner, soarranged within the separator as to deflect the heavier particles fromthe lighter and separate them respectively for distribution into theirproper receptacles.

Other objects of our invention are to render the cleaning of theseparator easier by making the segments of the plates movable and torender the liner more readily introduced into or removed from thecylinder by the compact arrangement of its plates when they arecompressed upon each other and against the liner.

These objects we accomplish in the manner and by the means hereinaftermore fully described in detail and particularly pointed out in theclaims, reference being had to the accompanying drawings, in which likenumbers indicate like parts throughout the several views.

Figure 1 is a side elevation of a separator in section, showing oursegmental conical plates pivotally mounted on the liner therein. Fig. 2is a top plan view of the segmental conical plates as seen from aposition indicated by the line at so in Fig. 1, and Fig. 3 is a detailshowing the segmental plates placed in different positions for thepurpose of cleaning them.

Our invention is intended particularly as an improvement on the PatentNo. 640,130, issued December 26, 1899, to Charles H. Hackett andChristian E. Dailey, of Waterloo,lowa, and the construction of theseparator-bowl is the same as shown therein. Our improvement, however,is capable of being adapted to conform to the interior construction ofother forms of separator-bowls.

The liner consists of the uprights 1, at-

tached at the top to the ring 3 and at the bottom to the ring 4.

The plates 2 and 2' are constructed in the form of segments of thesurface of a truncated cone of sufficient Width that they may overlapeach other when in a state of rest and are curved into such a shape thatwhen thrown out horizontally as an effect of cen- 6o of the outer edgesof each plate is so formed that only the middle portion thereof can comeinto contact with the inner periphery of the cylinder, those parts ofthe edge nearest the outer corners of the plate being cut awaysufficiently to leave a space between them and the inner wall of thecylinder 7 when in revolution. This is shown in Fig. 2 by the dottedlines, the outer dotted line indicating the position of the innerperiphery of the cylinder and the inner dotted lines the positions ofthe plates when pressed against the cyline der. The plates are hinged atthe middle portion of their lower edges by means of hinges 9, pivoted tothe outer edges of the ribs 1 in such a manner that each series of segmental plates is above the series of plates below, like surfaces ofinverted truncated cones, at any distance apart which may be considereddesirable. It is to be understood that any number of segmental plates orseries of plates may be used and that they may be pivoted to theuprights of the liner by any other suitable or equivalent form of hingeor pivot. The drawings represent the segmental plates as compressedagainst the liner in the position which they are placed when they areintroduced into the cylinder and indicate the ease with which they maybe placed within or removed therefrom. The dotted'lines represent themanner in which the plates spread 5 IOO milk on account of their greaterweight find their way to the inner wall of the cylinder, the lighterparticles of cream tend to find their way to the center. The skim -milkcoming in contact with the upper surfaces of the upper series ofsegmental plates finds its Way down the inner wall of the cylinderthrough the spaces left between the cylinder and the cut-down outeredges of the plates. The retarding of the descent of the milk by meansof the interposing plates allows the minuter particles of the cream notheretofore separated therefrom to become separated and flow toward thecenter of the liner along the under surfaces of the plates. This processby retarding the movement of the milk toward the bottom of the cylinderallows it to become completely exhausted of the minuter particles ofcream commonly wasted in the ordinary type of separator. The skim-milkis then discharged through the pipe 6, which opens into the separatornear its inner wall, while the cream is discharged in the usual mannerthrough the conduit at the center of the bottom of the separator at 5.

Instead of the separator 7 any other similar receptacle may be usedwherein our series of improved segmental plates can be inclosed arrangedto spread to meet the inner periphery of the bowl. This manner ofconstruction, embodying the pivotal attachment of curved plates in theform of portions of the surface of truncated cones to the inner liner,allows the apparatus to be easily introduced into or withdrawn from thecylinder of the separator when the plates are pressed up into closecontact with the liner. The pivotal attachment of the segmental, platespermits them to be easily moved up or down and cleaned, as is shown inFig. 3.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. In a centrifugal liquid-separator, a liner provided with series ofseparated plates in the form of segments of an inverted truncated conepivotally mounted thereon, sub stantially as shown and described.

2. In a centrifugal liquid-separator, a liner composed of the uprights 1attached to the rings 3 and 4C, in combination with the segmental plates2 and 2', pivotally attached thereto by the hinges 9, substantially asshown and described.

3. In a centrifugal liquidseparator,in combination, the cylinder7, theliner composed of the uprights 1 and rings 3 and 4, the segmental plates2 and 2 pivotally connected to the uprights 1 by hinges 9, allsubstantially as shown and described.
